Conditional Access System



Neurotronix Conditional Access System (CAS) can encrypt control words and user authorization information within a stable and highly secured environment. This system is 100% compatible with DVB simul-crypt standard, with high reliability and bi-directional interactive services. So that it could satisfy operators' various needs and requirements with high performance price ratio. In the bi-directional transmission network, our system could offer the interactive services, such as subscriber identification authority, online program ordering and audience survey.

CAS is considered as the core unit of complete DTV system. It has two main functions. One is cooperating with Scrambler to realize the scrambling of the TS, and the anther is to realize the encryption of CW (Control Word/Code Word). At the same time, the CAS needs to cooperate with the SMS and receive the authorization management information from it.
